Sony tells Eurogamer: PlayStation 4 will not block used games

                                                                                                        Sony Worldwide Studios boss Shuhei Yoshida has told Eurogamer that  PlayStation 4 will not block the use of second-hand games, contrary to  various reports, speculation and even a Sony patent unearthed last  month.
   I sat down with Yoshida a few hours after the PS4 reveal tonight  and one of the first things I asked was whether used games would be  blocked.
   "Do you want us to do that?" he asked.
   No, I said. I think, if you buy something on a disc, that you have a  kind of moral contract with the person you've bought it from that you  retain some of that value and you can pass it on.
   Do you agree, I asked?
   "Yes. That's the general expectation by consumers," said Yoshida.  "They purchase physical form, they want to use it everywhere, right? So  that's my expectation."
   So if someone buys a PlayStation 4 game, I asked, you're not going to stop them reselling it?
   "Aaaah," was Yoshida's initial answer, but seemingly only because  he'd forgotten his line. "So what was our official answer to our  internal question?" he asked his Japanese PR advisor. The advisor  stepped in but didn't seem to answer clearly, at least to my ears.  Yoshida then took control again firmly:
   "So, used games can play on PS4. How is that?"
   I said I thought that was fine. Interestingly, I also spoke to a Sony source elsewhere at the event this evening who told me that the anti used-game patent 
discovered last month was actually nothing to do with PlayStation 4 at all. The patent suggested that discs would come branded with a  contactless tag that could be recognised and read by your console, which  would then bind it to you and prevent you from selling it on. But whatever reason Sony did have for patenting it, it sounds like  it wasn't for its next-generation console. Hopefully Microsoft will also  avoid this ludicrous technology with its next-generation Xbox as well.
